Yes, that doesn't change my point. In both cases it looks like the ecosystem had multiple niches that in the fossil record previously having different species apparently all filled with a single species. With Trex, one of the current theories is that it filled different niches as it grew up.

Although with Trex, there may have been a half sized version that was hunting alongside the big one(s).
